Bought a Walker 4-core in 1985 for my 32 highboy.

Plugged the trans cooler and run an external one.

1993 got the car running.

The radiator did pop one horizontal seam at the top tank, got that repaired and no more trouble.

I also went to a 7# cap as recommended by the radiator shop.
(A 16# was on there previously.)

What I like about the copper/brass radiators is that they are serviceable in the field.
Far as I know that's not gonna happen with an aluminum radiator.
